Within a few short months El Dorado's population doubled, and before the year was out it doubled again, before peaking two years later at over 40,000. With the population explosion came oilmen from Louisiana and Texas, but also thousands of bums, promoters, and crooks arriving on daily trains. Within weeks of the discovery, barrelhouses with prostitutes, gambling, and whisky sprang up across from the railroad station on South Washington Street, which became known as Hamburger Row because of the hamburger stands there. During the first two years of the oil boom, Hamburger Row reverted to the lawlessness of the old West as El Dorado's small police force was unable to handle the chaos. On street corners young boys sold moonshine in six-ounce Coca Cola bottles for $1.25; prostitutes walked the streets, and dope peddlers like Smiling Jack and Weasel tugged at people's sleeves. Hamburger Row was filled with figures like Barrelhouse Sue, who came from Homer, Louisiana, following the boom and sang, danced, and solicited in places like Dago Red's, Pistol Hill, and Shotgun Valley. Two Shot Blondie, another madam, imported prostitutes and made moonshine deliveries and was well known on Hamburger Row and at Jake's Place, the biggest and most notorious barrelhouse, which boasted the prettiest girls in town. Big Ed, a giant of a man, served as a gang enforcer for the infamous Silvertop, one of the most feared men in South Arkansas, and Oscar and Joe were moonshiners who made door-to-door deliveries. Teams of oxen and mules, some as long as 20 pairs, pulled oil field equipment through the streets, and after heavy rain the iron-wheeled wagons turned most of the streets into quagmires so dangerous that some mules drowned.
